FIELD OF THE INVENTION

[0002] A child's seat, more specifically a child's seat capable ofengaging a wheeled luggage container.

BACKGROUND OF THE INVENTION

[0003] Applicant's invention relates to luggage containers andchildren's seats and a unique combination thereof. Recently, luggagecontainers have become popular, which luggage containers often includeat least a pair of wheels along a bottom edge thereof and a handle,frequently an extensible handle, engaging an upper surface thereof. Thehandle may be extended from the end of the luggage and the luggagetilted to form an oblique angle with a support surface such as anairport floor. This allows the easy wheeling of luggage across anairport, even heavy luggage, since the floor is supporting much of theweight of the luggage where the luggage wheels meet the floor. When thetraveler reaches their destination, the extendable handle may beretracted back into a suitable pocket along a wall of the luggagecontainer. One such suitcase is manufactured by Atlantic. Other similarluggage containers are manufactured by Skyway, Samsonite and otherleading luggage container manufacturers.

[0004] Applicant has recognized a problem that frequently occurs when afamily is traveling with young children. This problem manifests itselfin the often long journey through an airport to the desired gate whenthe adults must contend with luggage and small children in a crowded,noisy, confusing atmosphere. Applicant recognized that it would help ifa child could be confined, in a convenient way so as to prevent thechild from wandering off. However, the customary wheeled strollerrepresents a significant amount of bulk merely for the convenience ofconfining a child to a wheeled conveyance during movement through anairport. Applicant has discovered the unique invention disclosed andcontained herein, which novel invention provides a folding child's chairthat in a folded position will store conveniently within a luggagecontainer but in an expanded position will engage the wheeled luggagecontainer in a manner such that the chair is supported by the luggageitself and placing the child's weight over the wheels of the container.

SUMMARY OF THE INVENTION

[0005] What Applicant provides is a foldable child's seat capable ofengaging a luggage container, such as a luggage container having atleast a pair wheels. More specifically, the handle or top of the luggagecontainer acts as a support brace for engaging the foldable chair. Thefoldable chair includes a loop for engaging the extendable handle or tothe top of the luggage container and has a seat portion including a seatback and a seat bottom that are hingedly engaged so as to layperpendicular to one another and provide support for the buttocks andthe back of the child.

[0006] In its simplest embodiment, Applicant provides two platforms,hingedly engaged to one another so that a first platform, for example aseat bottom platform, may lay perpendicular to a second platform, forexample a seat back platform. From the seat back platform is hingedlyengaged a luggage attachment member, which member is designed andadapted to extend generally perpendicular to the seat back platform whenin a use position.

[0007] In another preferred embodiment, Applicant's seat includes a seatbottom frame and a seat back frame, the two frames typically made ofaluminum tubing and being generally rectangular and/or similarlydimensioned. The two frames are pivotally engaged to one another andinclude a cover, the cover typically being cotton, woven fabric, plasticor any suitable flexible member. A hinge engages the two platforms sothat they may be pivoted one respect to the other so they lay in afolded position parallel to one another and in an extended positionperpendicular to one another. The frames may support the seat cover toprovide a convenient resting place for the child or other weight. Fromthe seat back portion, a support loop may be pivotally engaged so it canlay, in a first or storage position, parallel to the two platforms ofthe seat and in an extended or use position, perpendicular to the seatback platform.

[0008] A number of advantages are achieved by Applicant's novel seat andthe combination of Applicant's novel seat with a wheeled, handleextendable luggage container. Those advantages include effectivelysecuring a child to the wheeled luggage container for ease of transportthrough, for example, an airport. The advantages include simplicity andcompactness, such that the foldable child's luggage chair is easy totravel with. The advantages of Applicant's novel design include ease inadapting the chair to the luggage as well as simplicity in themanufacture of the chair.

[0009] These and other advantages or objects are provided in a foldablechild's seat adaptable to engagement with an extendable handle or top ofa luggage container, the foldable seat including a generally rectangularseat bottom platform hingedly engaged to a generally rectangular seatback platform so that the two may fold together in a stored positionwhen they fold out in a use position, wherein in the use position thetwo platforms are perpendicular to one another.

[0010] The novel child's foldable seat chair for engagement with anextendable handle or the back wall of a wheeled luggage container mayalso include a support loop extending from the seat back platform, whichsupport loop has a removed end, the removed end for engagement with theextendable handle of the wheeled luggage container, the support loopfoldable so that it can lay in a stored position adjacent the twoplatforms and in the use position can extend perpendicular to the seatback platform.

[0011] Applicants provide additional embodiments of a child's seatengageable to a luggage carrier in providing a flexible strap forengaging a luggage carrier, typically at a handle, which flexible strapalso engages a fabric sling with a rigid bottom seat, for enclosing achild, typically from the waist down. The sling may have leg holecutouts in a front wall thereof, which front wall may be supported bystraps extending from the flexible luggage engaging a loop.

[0012] Yet a further embodiment of Applicants' present inventionincludes a child's chair with a pivotal armrest engaged to a seatbackframe, the armrest foldable between a closed or nonuse position and ause position, the use position being a position in which the armrest,supported by hinges or the like, extends perpendicular from the seatbackframe and provides a location for the child to rest his or her arms asthey are seated in the child's chair.

[0013] In yet a further embodiment of Applicants' present invention, apair of legs are adapted to extend obliquely outward from a lowerperimeter of the chair to engage the floor to prevent a child seated inthe seat with the seat engaged to an upright luggage carrier fromtipping forward.

[0014] In yet another alternate preferred embodiment of Applicants'present invention, a support arm or a support frame extendsperpendicularly downward from a forward edge of the seat bottom frame toengage the floor to help stabilize a seated child and prevent the seatfrom tipping forward as, for example, when attached to an uprightluggage container. A number of configurations are provided to achievethis function, some of which include means to adjustably set thedistance between the forward edge of the seat bottom frame and thefloor.

[0015] In a number of embodiments discussed above, Applicants disclosevarious means to provide engagement from a seat assembly, comprising aseatback frame and a seat bottom frame (or platforms) with the handle,the top, or the back edge of a luggage carrier.

[0016] In yet another alternate preferred embodiment of Applicants'present invention, means are provided to engage the seat assembly,typically at an upper perimeter or edge of the seat back frame orplatform, with a means to engage the body of the luggage containeritself, rather than an extended handle.

[0017] In yet another alternate preferred embodiment of Applicants'present invention, a foot support brace or frame is provided, foldablyarticulating with the seat assembly (typically from a forward edge ofthe seat bottom frame) to provide a place for a child to place theirfeet. This foot bar assembly may incorporate an adjustable downwardlydepending leg or legs which will engage the floor to provide stabilityto a child seated in the chair when the chair is engaged to the luggageto prevent, for example, the chair assembly tipping forward.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0031] Reference to FIGS. 1 through 5, illustrate, at the outset, aluggage container (LC) having wheels (W) and a handle (H). The luggagecontainer illustrated is merely representative of many similarly wheeledand handled luggage containers of the prior art, having a number ofdifferent shapes and sizes and construction designs. Applicant's novelfoldable child's seat (10) is designed, as illustrated in FIG. 1 toengage the handle and walls of the luggage container (LC) in a mannerset forth below, so as to provide a comfortable, sturdy seat in whichwhen attached to the luggage container, a child may ride.

[0032] It is seen that the general construction of the foldable child'sseat (10) includes a seat bottom frame (12) hingedly engaged to a seatback frame (14), the two frames being able to lay in a folded positionadjacent one another or in an open position perpendicular to one other,the two frames covered by an L-shaped cover (22). The seat back frame(14) has a support loop (16) hingedly engaged therewith, the supportloop for engaging the extendable handle of luggage container (LC) suchthat the loop lays along a top surface of the luggage and the seat backframe lays perpendicular the loop and adjacent, and typically flushagainst a sidewall of the luggage (See FIG. 1). With the seat frameextending perpendicular to the seat back and sidewall of luggage, thecombination of seat back and seat frame provides support to the back andbuttocks and legs of a child when the child is seated in the foldablechild's seat chair (10) and the seat chair (10) is engaged to theluggage container (LC) so as to ride on wheels (W) when tilted.

[0033] Platforms may be used instead of seat bottom and seat backframes, however, a preferred embodiment of Applicant's present inventionutilizes frames and fabric covers for lightness and simplicity. Indeed,reference to the figures illustrate a seat bottom frame (12) including afront rail (12A), side rails (12B and 12C) and rear rail (12D). Seatback frame (14) may include top rail (14A), side rails (14B and 14C) andbottom rail (14D). Support loop (16) as provided may include an end rail(16A), two side rails (16B and 16C) and a rear rail (16D). A first hinge(18), such as a piano hinge or any other suitable hinge device isprovided for engaging seat bottom frame (12) to seat back frame (14).This is typically done by hingedly connecting rear rail (12D) of seatbottom to bottom rail (14D) of seat back. A support loop is providedwith a second hinge (20), for attaching the rear rail (16D) of thesupport loop to the top rail (14A) of the seat back frame.

[0034] The frame and support loop and the rails defining the frame andsupport loop may be manufactured from lightweight, durable aluminumtubing or any other suitable material. Cover (22) may be L-shaped andtypically includes fabric defining an outer surface (22D) and innersurface (22E) separated by sidewalls (22F), the outer surface and innersurface defining an interior space that will slip over the seat bottomand seat back frame snugly so that the sidewalls (22F) engaged the siderails and front rail of the bottom frame and the side rails and the toprail of the seat back frame so that the fabric is what supports thechild's weight, especially the fabric stretched between the sidewalls ofthe seat bottom frame. Cover (22), therefore includes a seat bottomportion (22A) and a seat back portion (22B). Side panels (22C) haveedges that engage both the seat bottom portion and seat back portion asillustrated in FIG. 2 so that the side panels position the seat back andseat bottom in perpendicular relation when the foldable seat (10) is ina use position as illustrated in FIG. 1.

[0035] Seat bottom frame, seat back frame and support loop may be foldedto a closed position as illustrated in FIG. 5 and Applicant provides asuitably dimensioned fabric stow bag (28) dimensioned for receipt of thefolded chair thereinto. Other features of Applicant's novel foldablechild's seat may be appreciated with reference to FIGS. 1 and 5. Forexample, a seat/chest belt (24) may be provided for a 2, 3, 4 or 5 pointsuspension system, here illustrated with a 3-point suspension systemincluding a chest and/or seat strap (24C) and a antisubmarine strap(24B), the three straps defining a 3-point suspension system engagableat buckle (24A). A 5-point system would include a pair of shoulderstraps (not shown).

[0036] The seat and/or chest belt (24) is designed to secure the childto the seat. An adjustable seat loop or securement strap 26 is designedto the secure seat assembly to the luggage container (LC) in the mannerillustrated in FIG. 1 such that the back of the seat lays snug againstthe sidewalls of the luggage container. However, as is apparent withreference to FIG. 1, it can be seen that Applicant can provide a seatsecurement strap (26) for attachment to the seat back and/or seat bottomand capable of wrapping around the walls of the luggage to hold the seatback snug against the walls of the luggage container so as to act inconjunction with the support loop to secure the foldable child's seat(10) to luggage container (LC).

[0037]FIG. 6 illustrates the use of rigid platforms (30), (32) and aflexible cord or strap (34) in place of the rigid support loop. The cordor strap (34) may be adjustable. In this embodiment, only a single hinge(36) is necessary and side braces (38A), (38B) will hold the platformsperpendicular to one another when in use.
